Ring Sizes

Measuring your ring size at home can be done easily with a few simple steps:

  • Wrap a string or strip of paper around your finger and make sure it is snug but not too tight. Mark the spot where the ends of the string or paper meet.
  • Use a ruler to measure the length of the string or paper. Make sure to measure it in millimeters (mm) as ring sizes are measured in millimeters.
  • Compare your measurement to the ring size chart bellow.

You may also want to measure your finger at different times of the day, as fingers can change size due to temperature or swelling. It is recommended to measure your finger size at the end of the day, when your fingers tend to be at their largest.

If you are still unsure of your ring size, it is best to visit a jeweler for a professional measurement.

It's important to note that if the ring is a surprise gift, you can measure one of the ring the person already have and use that measurement as reference.

Keep in mind that ring sizes can vary slightly and it's better to choose a slightly larger size than a smaller one, as it's easier to resize a ring that is too big than one that is too small.
